摘要
从误比特率的角度分析了基于雪崩光探测器(APD)和直接检测(DPIM)无线光通信系统在弱大气湍流中的性能特点。仿真分析结果表明,系统性能随接收机热噪声的升高而降低,随大气湍流强度的升高而降低,存在最佳 APD 平均增益值使系统的性能达到最优。
Performance characteristics of the direct-detection,avalanche photodiode-based on APD and DPIM optical wireless communication system over weak atmospheric turbulence in terms of bit error rate is analyzed. Simulation results show that the performance of such a system is impacted by receiver thermal noise and turbulence, and it also shows that an optimum average APD gain can be used to achieve the best system performance.
